Wisdom tooth removal takes out one or more back molars that are impacted or causing pain, infection or other problems.
Quick answer
Wisdom Tooth Removal: what it is, why it's done and what happens
Wisdom tooth removal extracts the third molars at the back of the mouth. These can become impacted (stuck) against other teeth or the jaw, and are removed by a dentist or oral surgeon.
- Why it is done: It is used when wisdom teeth cause repeated infection, decay, gum disease, cysts, damage to nearby teeth or persistent pain.
- What happens: It is done under local anaesthetic, sometimes with sedation or general anaesthetic for difficult cases.
What it is
Wisdom tooth removal extracts the third molars at the back of the mouth. These can become impacted (stuck) against other teeth or the jaw, and are removed by a dentist or oral surgeon.
Why it is done
It is used when wisdom teeth cause repeated infection, decay, gum disease, cysts, damage to nearby teeth or persistent pain. Teeth that are not causing problems are often left in place.
What happens
It is done under local anaesthetic, sometimes with sedation or general anaesthetic for difficult cases. The surgeon may need to make a small gum cut or remove some bone, and stitches may be used.
Recovery
Swelling, soreness and jaw stiffness are common for a few days. Soft foods, pain relief and salt-water rinses help. Most people recover within a week, avoiding smoking and vigorous rinsing early on.
Good to know
Risks and things to consider
Risks include pain, swelling, bleeding, infection, a painful dry socket, and — for lower teeth — temporary or rarely lasting numbness of the lip, chin or tongue from nearby nerves.

Answers
Wisdom Tooth Removal: frequently asked questions
Do all wisdom teeth need to be removed?
No. Wisdom teeth that are healthy, correctly positioned and not causing problems are usually left alone. Removal is recommended when they cause pain, infection or damage.
What is a dry socket?
A dry socket is a painful condition where the blood clot at the extraction site is lost or fails to form, exposing the bone. It usually settles with treatment; avoiding smoking and vigorous rinsing lowers the risk.
